(Punishment was often delayed) until when the messengers were in despair and thought that they were wrong in their estimation, Our help came to them, then saved were those whom We willed. And Our punishment is not averted from the guilty. Surely, in the narratives of these, there is a lesson for the people of understanding. It is not an invented story, rather, a confirmation of what has been before it, and an elaboration of everything, and guidance and mercy for a people who believe. (Surah Yousaf, Verses 110 & 111 – Translated by Taqi Usmani)
